title: [The parenchymatous-stromal interrelationships in adenocarcinomas of the large intestine (an electron radioautographic study)].
abstract: Parenchymatous and stromal cells in colonic adenocarcinomas were studied electron-radiographically. The properties of the nucleic acid and protein synthesis in the cylindrical and goblet cells in carcinoma (partial 3H-thymidine incorporation, heterogeneity of 3H-uridine and amino acid mixture incorporation) indicate a relatively low level of their differentiation, lower degree of their participation in a specific function, retaining their capacity to proliferate. A high number of 3H-thymidine-labelled stem cells which are the main source of tumour growth is observed in carcinoma. Stroma in carcinoma is characterized by endotheliocyte and fibroblast proliferation (3H-thymidine incorporation), high degree of metabolic processes in some of these cells (3H-uridine and amino acid mixture incorporation) and by the disturbance of immunocompetent cell specific function (partial and weak labelling of the immunocompetent cells with 3H-uridine and amino acid mixture).
